I’d never let my kids (or grandkids, now that the kids are grown), play in a tree with foliage touching power lines.
In 1989, we were sent on “storm damage” in Pearl, MS after an ice storm. All the crews had been dispatched to work on clearing downed lines, and we were sent to do some routine trimming. The line we were on ran down a fence row where the trees had been topped/retopped over and over. Our lines here are like 7.2KV...theirs were in the 2KV range. I lost count of how many times I got buzzed in those trees when the wind would blow a limb into the line. I felt it through my hooks and hands.
Trimming a whippy yard pine not far from here that same year, I’d climbed and cut all I could, then had a pruner sent up to clip the rest. I clipped a particularly contrary “limb” that chose to torpedo down my shirt collar, then brush the primary as it fell. I figure Michael Jackson would have been proud of me for about two seconds...
